NITED OSCAR A. SMITH ALBERT J. WEATHERHEAD, JR., 0] CLEVELAND, OHIO.

Application filed May 19, .1921. -Serial No. 470,921.

To all whom it may concern Be it known that-we, OsoAR A. SMITH andALBERT J. WEATHERHEAD, J r., citizens of the United States, residing atCleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain newand useful Improvements in Drain Cocksfof which the followingis a specification.

This invention relates to drain cocks, prefera'bly adapted to be usedwith radiators or engines of automobiles, an object thereof being toprovide an improved drain cock having a valve openable in a directionopposite to the direction of flow of the fluid from the radiator orcarburetor, the construction being such that accumulations such assediment or impurities will not pass into a drain chamber and choke thesame, and such accumulation or sediment caked around 'the top of thevalve will be readily broken away or dislodged upon shifting the valveupwardly to open the same.

A further object of this invention is to provide a drain cock embodyingcertain improvements over Patent #1345932 for drain cocks, dated June29, 1920, and which can be manufactured readily at a minimum of expense,will be simple in construction, and efi'ective and durable in use.

Other objects of this invention will appear in the following descriptionthereof reference being had to the accompanying drawing forming a partof the specification wherein like reference characters indicatecorresponding parts in the several views and wherein Fig. 1 is a sideview partly in section, illustrating the drain cook closed; Fig. 2 is asimilar view illustrating the drain cock open; Fig. 3 is a perspectiveview of our improved drain cock, parts being broken away; Fig. 4 is aside'sectional view of another embodiment of our invention; and Fi 5 isa perspective view thereof.

Tn its preferred form herein shown and described our improved draincock, although preferably constructed for use with radiators ofautomobiles or tractors, is of course adapted to be used for variousother purposes such as with internal combustion en gines, carburetors,or the like. Th1s improved drain cock in the present instance, asillustrated, comprises a body member 2 threaded at one end 3 topreferably permlt the same to be secured to the bottom of a radiator orother fluid carrying receptacle,

illustrated in part at 4, designed to permit the reception of sedimentor other accumulations. Although inthe present case we have illustratedour improved structure as adapted to be threaded into the bottom of aradiator, it is of course understood that we do not limit ourselves tosuch use but it will be readily seen that the threaded portion 3 of thebody member 2 will be secured in any manner depending upon theparticular structure with which our invention is used. The body member 2is provided intermediate its length with a wrench receiving portion 5, I

and at the end opposite to the threaded portion 3, with a threadedportion 6 preferably provided with exterior threads. The body.2 is alsodrilled to form an axial passageway? therethrough and terminates at oneend, in-

the present instance, the upper end, in a valve seat 8 preferablystraight walled, Figs.

2 and 4. The same may be tapered at '8' if desired. p

The valve in this device comprises a head 9 provided with a tapered facecooperating with the valve seat 8 and an elongated stem 10 formedintegrally therewith. This stem is adapted to extend into the passage 7and is herein shown as spaced from the walls of the passageway 7 inorder to provide a channel for the flow of fluid through the bodymember. If desired the valve stem may be constructed in the mannerillustrated in the aforesaid patent, the fluid flowing through the valverather than around the same.

A chambered or cup-shaped operatin member 12 interiorly threaded isconstructed to be secured to the threaded portion 6 of the body member,and by virtue of the cooperating threads is shiftable relativelythereto. It will be seen that one end 11 of the stem 10 projects intothe interior of the operating member 12. This member terminates in anaxial opening 13 and is provided with a-chamber 14: of any desired shapeor capacity. The valve stem 10- is secured interiorly of this chamberedmember 12. In the present instance this is accomplished by means of apin 15 driven through or inserted into alined holes or openings drilledthrough the end 11 of the valve stem and the walls of the member 12.

In the embodiment illustrated in Figs. 1, 2, and 3 the member 12 isprovided with a wrench receiving portion 16, in the present instance ofhexagonal configuration, and the pin 15 does not project beyond theouter walls thereof. This structure is preferably adapted for radiatorsin tractors. Due to the fact that the radiators of such machines areusually very close to the ground, it is important that all projectingoperating handles or the like be eliminated in order to pre ventaccidental opening of the valve. For ordinary automobiles the structureillustrated in Figs. 4 and 5 may be used if desired, in which case thebody member 12 is not provided with a wrench receiving portion, but, onthe other hand, the pin 15 projects through the cup-shaped portion 12and serves not only as a means for securing the stem and member 12together but also as an operating handle for manipulating the parts.

In operation it will be readily seen that by shifting the chamberedmember 12 relatively to the body member 2, the valve also will beshifted in the same direction in order to open or close the same. Thevalve is opened in a direction opposite to the direction of flow of thefluid thereby enabling the same to dislodge or break away any foreignmatter which may have caked around the top of the valve head while inits closed position. By providing the member 12 with a chamber 14greater freedom for the flow of fluid is provided and the scope of useof the device is broadened and increased.

In the embodiment illustrated in Figs. 1 to 3 inclusive the valve itwill be understood is readily operated by means of a wrench applied tothe portion 16, and in the embodiment illustrated in Figs. 4 and 5 thevalve will be operated by grasping the handle 15 and turning the member12 in the desired direction.
